Diffyn's answer

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries.

We started Spkwith after years of watching teams stare at numbers but still not know what their users were thinking. We wanted to bridge that gap, to make it easy for any company to ask the right question at the right time and finally see what really drives behavior.
